PETG 3D Printer Filament 1.75mm,Multicolor,Chameleon,Color Change with Light and Angle,1kg(2.2lbs) Accuracy +/-0.05mm for ender3 Cr10

This is a hard review to write... on the one hand, this cost me $12 for a roll but on the other hand, there's issues. Overall though, it's considerably better than I could expect given the price.I've just finished off my first roll, and I have strong opinions. First off, the colour is great. Dark black with a nice gloss. Once properly tuned, it prints very well with no real bed or layer adhesion issues. It's PETG, but doesn't string too much once dialed in, and bridging is possible (though not great, it is still PETG). I had no issues with clogging nor blobbing issues beyond what I have with other PETG, and there were no tangles in the filament. It's also $12 for a roll.Now onto the things to be aware of... first off, the diameter is very inconsistent... ranging from 1.62 to 1.76 in the same roll. Those measurements are the average of 90° at the same place with a calibrated micrometer. This filament was oval at every place I measured it, and I measured it *a lot*. For small prints, you can get away with unrolling all you'll use, measuring it then average it. Be sure to measure at right angles at each point because it will be oval. For larger prints, it's best to set the diameter to 1.75 and expect some minor underextrusion.Next is the finish... when printed at 4mm³/s (regardless of hotend speed or layer height) the finish is a matte black. When printed at 3mm³/s and lower, it's nice and shiny. Since your hotend will accelerate and decelerate during the print, printing 4mm³/s or higher means some high gloss areas and some matte areas. You really need to keep the volumetric rate very low, even for PETG if you want to look at the print. This does not seem to impact layer adhesion or anything else, so for hidden functional parts, faster is fine.Because of the above issue, this isn't a good every-day PETG to leave on your printer, rather this is one to pull out when price matters and quality doesn't... prototypes, kinematics tuning, things with lots of supports that can take a long time to print etc. If you try to print everything with this you will get frustrated and stay that way.All of that said, I'm going to be keeping a couple rolls of this in my dry box at all times from now on, but only until something cheaper comes along. This is bargain basement filament only for use when price is the most important factor. When *anything* else matters, spend more and use something better.

The only thing I could complain about is that Stronghero3d doesn't offer the blue, teal, and purple found in this filament as stand alone color options. Liked it so much I immediately ordered another roll.The picture shows a custom keyblade design that assembles with no glue or fasteners. I think it shows how well this filament really performs.Use a gluestick and enjoy this great color changing filament. The finish is like a fishing boat paint, sparkly.

(This filament is the dark blue print in the photo, light blue print is an unrelated cheap PLA)I was skeptical of the quality of this PETG for the price but I'm pleasantly surprised. There is not a lot of color change, but a subtle light to dark shift in prints. There is some glitter in the filament, but not so much that I've had issues with it printing with a .4 nozzle on my Bambu X1 Carbon. After printing about 200 grams of the spool, I've had no stringing, no clogs, okay bed adhesion with glue stick and a 70c bed, and prints look great at 100% speed.

This was my first experience with PETG, and I was told that I need an all-metal extruder to work at high temperatures. So I upgraded the extruder and calibrated accurately the PT100 temperature sensor to know exactly at which temperature to run. To my surprise, the working temperature of 220-225C appears to be best and there is no need to go higher. At this temperature the feed is clean, and there is not a lot of stringing when extruder travels far between draws. It does not work well for me at higher temperatures - stringing, teardrops appear more frequently. I also noticed that my Ender3 printer originally reported temperature 10-15C higher than actual. The recommended temperatures on the spool are 230-260C, but probably it is specified for uncalibrated out of the box printers - I had worse results at these temperatures. But at higher temperatures this filament is still not stuck in the extruder as other PETF filaments do. I still see not best adhesion on thin walls (2 lines) so the part may break on the layer line. I did not figure out yet what can be done to improve it.

The StrongHero3D PETG filament is one of the more unique filaments I’ve printed with.Overall, the quality is great and printed with ease on my PRUSA MK4 right out of the package (no drying, etc.).The filament is supposed to be transition, but as you can see in the pics it is not noticeable. On a much larger print, I think you’d see more gradient.The filament is very translucent which gives a cool effect. I’ve printed a few different models with this filament and I would recommend!

I've tried 3 prints and this stuff clogged on ALL 3 of my prints. The filament looked like it had dust or something all over it. I cleaned it off best I could. When its printing, its printing well. Unfortunately I cant seem to get a print through without it clogging multiple times. Luckily my machine is sensing the clogs, but on partial clogs its still pushing through as seen in the picture above. I was planning on printing some dragons, but if I cant go 4 hours without a clog there no way I am attempting a 10 hour print. I have been printing with PETG for 11 years now and this is the most difficult filament yet. I got a brand new IDEX printer with new nozzles. Im going to swap out my nozzles with .4mm to .6 or .8 and see if its any better before I ruin a brand new nozzle with 8 hours of printing on it. All 8 hours are with this material! I bought multiple spools. I didn't get a clog on my second machine till about 20 hours into my filament. That's about half way through the spool. About to upscale the nozzle size on that machine too to see if this filament is salvageable.

Good print quality and easy to work with. Unlike the PLA that I bought from this company, this is properly spooled and went smoothly through my extruder. The prints are well done and the filament seems to be very consistent throughout the spool.

Low quality and uneven size , some spots are really thin , it has happend 4 times alredy in like 150g of fillament , u can see on picture for yourself will not buy again

First off, PETG is PETG and I didn't find that this was stringing or fussing any more than anything else I have printed. Granted, I don't use this material for smaller detailed pieces, I usually print larger scale stuff that has to be tough and this filament never let me down for those purposes.Awesome price and fantastic quality if you've got your machine dialed in, definite recommendation!

I have been using Cura on my Creality Ender 3 and once I had the settings tuned for this filament, my prints have been looking great. I print slower than normal on a hairspray coated glass bed so I can have a really high quality finish on my parts. Let your print cool to room temperature and use a safety razor blade to get under the brim/part and let air flow in slowly, it will simply pop off the glass plate.Cura Settings:Start with Cura generic PETGLayer Height: 0.2Line Width: 0.5Wall Thickness: 1.0 (or 3.0 for really strong parts)Top/Bottom Thickness: 1.0 (or 3.0 for really strong parts)Optimize Wall Printing Order: yesPrint Thin Walls: yesZ Seam Alignment: randomInfill Density: 20% (50% for very strong parts)Infill Pattern: CubicPrinting Temperature: 240CBuild Plate Temperature: 95C (this is important, my print bed was a full 20C cooler on the my camera!)Flow: 100%Wall Flow: 108%Top/Bottom Flow: 76%Skirt/Brim Flow: 116% (you need a vacuum seal between the bed and part for excellent bed adhesion)Initial Layer Flow: 104%Print Speed: 30mm/sWall Speed: 8mm/sTop/Bottom Speed: 15mm/sTravel Speed: 150mm/sInitial Layer Speed: 4mm/s (this is important, print very very slow to get fine details to stick to glass)Skirt Brim Speed: 4mm/sEnable Retraction: yesRetract at layer change: yesRetraction Distance: 5mmZ Hop When Retracted: yesCooling Fan Speed: 50%Build Plate Adhesion Type: Brim (this is important, you need a vacuum / suction cup type seal to keep the parts on glass)Brim Width: 8mm

This Petg is easy to print despite all the negative reviews listed here. Do your research, set a baseline for your print settings and tweek one parameter at a time until you get your desired quality. Set your print speeds lowers the Pla at first.Petg is proned to stringing. Try turning off your retractions off completely to start and see if it prints well enough for you at first. If you get excessive stringing, try lowering your print temps in increments.On my Prusa I3 Mk3, i can print sucessfully at 70mm/s at 235C, with retractions off.This petg has a beautiful transparent blue color with a shiny sheen on finished prints. Its translucent with low infill and a deep jewel look with denser infills. Its much stiffer and stronger then generic PLA turned out great when printing parts that have stress points and wear areas where PLA would just crack or snap off.
